WASHINGTON — The Justice Department has decided not to charge David Petraeus’ mistress, Paula Broadwell, with cyberstalking as part of its investigation into an e-mail scandal that led to the resignation of the CIA director and storied general.

Petraeus resigned as CIA director in November after acknowledging the extramarital affair, which was exposed after Broadwell e-mailed Tampa socialite Jill Kelley, allegedly warning Kelley to stay away from Petraeus and Gen. John Allen, the U.S. commander in Afghanistan.

Kelley reported the e-mails to the FBI, triggering an investigation that led the FBI to Kelley’s e-mails to the married Allen, who is now under investigation by the Pentagon’s inspector general.

A spokesman for Broadwell says she and her family are “pleased with this decision and pleased that this is resolved.”

Broadwell, Petraeus’ biographer and a reserve Army officer, is still being investigated by the Pentagon for allegedly mishandling classified information. FBI investigators found a “substantial amount” of material marked classified at her home.

The 7,800-acre Winter Valley Fire in Moffat County was 100 percent contained Tuesday as visible smoke from interior islands showed minimal creeping behavior, according to the Bureau of Land Management.
